Reconstitution of Light-Harvesting Complexes from Chlorella fusca (Chlorophyceae) and Mantoniella squamata (Prasinophyceae)
1993
Abstract Reconstitution experiments of light-harvesting complexes were performed with the green alga Chlorella fusca and the chlorophyll c-containing prasinophyte Mantoniella squamata using a modified method according to Plumley and Schmidt [Proc. N atl. Acad. Sei. U .S.A . 84, 146 -150 (1987)]. Changing the pigment supply quantitatively or qualitatively in the reconstitution mixture homologous and heterologous reconstitutes were obtained. In contrast to higher plants, light-harvesting polypeptides from green algae are able to bind the chlorophylls as well as the xanthophylls in different stoichiometries. Heterologous reconstitutes of M . squamata polypeptides give further evidence for a r…
A chemometric approach to evaluate the impact of pulses, Chlorella and Spirulina on proximate composition, amino acid, and physicochemical properties…
2019
Changes in physicochemical parameters, proximate composition, amino acid and taste profiles of turkey burgers enriched at 1% with soy (control), pulses, Chlorella and Spirulina proteins were studied. Results: Color parameters, pH, ash content, total, essential and non-essential amino acids were significantly different among the different type of turkey burgers prepared. In this regard, turkey burgers made with pea protein presented the highest values for pH and lightness, whereas the samples prepared with broad bean showed the highest redness. The inclusion of bean and seaweed produced a marked increase of glutamic acid, lysine and aspartic acid. However, the taste profile was similar in th…
Joan Roís de Corella, La Istòria de Leànder y Hero: edizione critica con studio introduttivo
2018
This contribution is a further partial anticipation of the critical edition of the mythological faules of Joan Roís de Corella (15th century) for Barcino (ENC), after that appeared in Magnificat, vol.3, 2016. It focuses on one of the author's most mature and significant faules, as well as one of the most prestigious testimonies both of the presence of the myth of Ero and Leandro in the Iberian 15th century, and of the peninsular reception of the Heroides. The paper consists of two parts. In the first part, Introduction, the current situation of the studies related to the Istòria is first summarized. Next, the analysis of the literary memory that supports the discursive construction of the f…

Mercenari italici in viaggio verso l’entroterra della Sicilia? Il contributo delle evidenze numismatiche e archeologiche
2014
The subject of the contribution is the analysis of a series of numismatic evidences, coming from Amorella, Monte Raffe, Castellazzo di Marianopoli, Santa Caterina di Villarmosa, through which it is possible to observe how, from the mid-4th century BC, the hinterland had become a veritable enclave of mercenaries. These are allogeneic groups, who presumably arrived in Sicily from the Italian peninsula to serve as soldiers in the ranks of the Dionysian armies, and were subsequently exhorted or chose to settle permanently in the indigenous communities of the interior
Pulsed electric field (PEF) recovery of biomolecules from Chlorella: Extract efficiency, nutrient relative value, and algae morphology analysis
2023
This study investigated the effects of pulsed electric field (PEF) (3 kV/cm, 44 pulses, 99 kJ/kg), solvent (H2O or 50 % DMSO) and time (0, 10, 20, 30, 60, 90, 120 and 180 min) on the extraction of Chlorella antioxidant biomolecules and minerals. The results showed that PEF treatment increased the biomolecules recovery. For the extraction time of 120 min, more proteins and polyphenols were obtained using water, while more chlorophyll a and b, and carotenoids were obtained using 50 % DMSO as the extraction solvent. The extracts mineral concentration (PEF vs control) were analysed including Mg, P, Ca, Fe and Zn, and the Relative Nutrient Values results indicated that Chlorella H2O-extracts cou…
Chronic toxicity of methylparathion to the rotifer Brachionus calyciflorus fed on Nannochloris oculata and Chlorella pyrenoidosa
1993
The effect of sublethal levels of methylparathion (0,1, 3, 5, 7 mg 1−1) on the freshwater rotifer, Brachionus calyciflorus, during their entire life cycle was studied. Rotifers were fed on two species of unicellular algae: Nannochloris oculata and Chlorella pyrenoidosa; both algal concentrations were 5 × 105 cell ml−1.
Morphological determination of the phototrophic community composition of biological soil crusts in coastal sand dunes in northern Germany
2022
This dataset comprises the microbial community composition of biological soil crusts in north-German sand dunes. For this we obtained enrichment cultures of phototrophic microorganisms, by placing fragments of biocrusts of the same Petri dishes as used for sequencing, in Petri dishes with Bold Basal (1N BBM) agarized medium (Bischoff and Bold 1963). Cultures were grown under standard laboratory conditions: with a 12-hour alteration of light and dark phases and irradiation of 25 μmol photons m-2 s-1 at a temperature 20 ± 5 ºС. Microscopic study of these raw cultures began in the third week of cultivation. Morphological examinations were performed using Olympus BX53 light microscope with Noma…
Les dones, l’amor i una elegia eròtica d’Ovidi en la vida i en l’obra poètica de Roís de Corella
2014
Resum: Roís de Corella fou un escriptor amb relacions amoroses juvenils, però amb fortes conviccions morals, que el portarien per un camí de perfecció i elevació espiritual, cosa que justifica la seua evolució temàtica. L’estudiant de teologia pren distància respecte dels predicadors medievals, però s’inspira en els clàssics llatins per a desenvolupar la seua creativitat literària i orientar-la cap a lliçons morals, amb un estil que crea escola. Fins i tot s’atreveix, als 23 anys, a transformar una elegia eròtica d’Ovidi –cristianament rectificada– en la Tragèdia de Caldesa: un experiment literari que fou molt aplaudit. . Paraules clau: Roís de Corella, Lletra consolatòria, Tragèdia de Cald…
The impact of liquid-pressurized extracts of Spirulina, Chlorella and Phaedactylum tricornutum on in vitro antioxidant, antiinflammatory and bacteria…
2022
The impact of Spirulina, Chlorella and Phaeodactylum tricornutum (P. tricornutum) microalgal extracts obtained by pressurized liquid extraction (PLE) on antioxidant and anti-inflammatory activities, microbial growth and in vitro gut microbiota composition was evaluated. PLE, compared to conventional extraction, led to a significant (p < 0.05) increase in proteins, carbohydrates, polyphenols, and antioxidant capacities of the three microalgal extracts. Moreover, Spirulina and P. tricornutum extracts significantly (p < 0.05) reduced the in vitro activation of the inflammatory NF-κB pathway. The microalgal extracts had also an inhibitory effect on the pathogenic bacteria while potential benefi…
